Database Description

As one database with two functionally different web interfaces, PlantsP and PlantsT are plant-specific curated databases that combine sequence derived information with experimental functional genomics data. PlantsP focuses on proteins involved in the phosphorylation process (i.e. kinases and phosphatases), whereas PlantsT focuses on membrane transport proteins. Experimentally, PlantsP provides a resource for information on a collection of T-DNA insertion mutants (knockouts) in each kinase and phosphatase, primarily in Arabidopsis thaliana, and PlantsT uniquely combines experimental data regarding mineral composition (derived from inductively coupled plasma atomic emission spectroscopy) of mutant and wild-type strains. Both databases provide extensive information on motifs and domains, detailed information contributed by individual experts in their respective fields, and descriptive information drawn directly from the literature. PlantsP is available at http://plantsp.sdsc.edu and PlantsT is available at http://plantst.sdsc.edu.

Recent Developments

The original PlantsP database has been extended to include PlantsT as a second view based on a common data and software model. A proteotyp system for acquiring and peer-reviewing user annotation has been implemented and is in use with over 200 registered users.
